Elastic wave propagation in complex geometries: A qualitative comparison between two high order finite difference methods
Kristoffer Virta, Christopher Juhlin, Gunilla Kreiss
We compare two high order finite-difference methods that solve the elastic wave equation in two dimensional domains with curved boundaries and material discontinuities. Two numeric…
High order finite difference methods for the wave equation with non-conforming grid interfaces
Siyang Wang, Kristoffer Virta, Gunilla Kreiss
We use high order finite difference methods to solve the wave equation in the second order form. The spatial discretization is performed by finite difference operators satisfying a…
Convergence of summation-by-parts finite difference methods for the wave equation
Siyang Wang, Gunilla Kreiss
In this paper, we consider finite difference approximations of the second order wave equation. We use finite difference operators satisfying the summation-by-parts property to disc…
